MARKER.

Application filed April 3,

To all whom it may concern:

Be it known that I, CHARLES B. MoGAL- LUM, a citizen of the UnitedStates, and a resident of Oakland, county of Alameda, State ofCalifornia, have invented a new and useful Marker, of which thefollowing is a specification.

The present invention relates to improvements in markers designedparticularly to be used by carpenters for marking face and edges ofboards to he fitted against abutting boards. One particular instance inwhich my device may be used is the fitting of the side: piece of a dooror window casing between two end pieces or between the top piece and thefloor or the base of the window. Another instance in which my device maybe used is the fitting of a base board against the frame of a door. Theparticular object of the invention is to provide means whereby themarkings may be taken from the abutting piece so that a correct fittingwill be obtained even if the abutting piece is not disposed at a rightangle to the piece to be abutted. If an ordinary square is used for thispurpose and the piece to be fitted in is cut at right angles it-frequently happens that the fit thus ,obtained is not perfect due tothe fact that the door opening is not exactly rectangular. When mydevice is used it does not make any difference whether the opening isstrict ly rectangular since the measure is taken from the member towhich the piece to be cut is to be fitted.

The preferred form of the device is illustrated in the accompanyingdrawing in which Figure 1 shows a plan View of the same, Figure 2 a sideview, Figure 3 a partial view in front elevation of a windowillustrating the manner in which my device is to be used, Figure 4 anend view of the illustration shown in Figure 3, Figure 5 a furtherillustration showing the use of my device in a different situation,Figure 6 another view illustrating the use of my device in connectionwith a base board to be fitted, Figure 7 a perspective view of amodified form of a marker and Figure 8 a detail view showing anotherslight modification in my marker. While I have shown only the preferredforms of my invention in connection with certain uses for the same Iwish to have it understood that various changes or modifications may bemade within the scope of the claims hereto attached 1923. Serial No.629,684.

and that various different uses found for my device without departingfrom the spirit of the invention.

In its preferred form my marker (1) comprises a rectangular plate (2)having parallel front and rear edges (3) and (4) and having flanges (6)extending preferably at right angles from the side edges. The frontedges: (7) of the flanges are parallel to one another and preferably ar\ranged 1n the perpendicular plane of'the front edge (3) of the plate.The rear ends (8) of the flanges preferably projectbeyond the rear edgeof the plate so that the rear edges (8) which are parallel to oneanother are disposed rearwardly of the rear edge (4) of the plate by anequal dis- 'tance.

The proper use of my device is illustrated in F igures 3 to 6. Assumingthat in a window frame the stool (9) and the top member (11) have beensecured in their respective positions and that it is now desired to fitthe side pieces (12). As illustrated in Figure 5 the side piece to befitted is first set on end on the stool (9) in the manner illustrated inFigure 5 and my marker is placed over the side casing with its rear edge(4) pointing downwardly and its two flanges (6) resting on the stool(9). Since the rear projections of the two flanges (6) are of equallength a pencil line drawn along the rear edge 1-) of the plate will beexactly parallel to the surface of the stool no matter whether the anglebetween the stool and the side piece (12) is an exact right angle ornot. The side piece is then out along this line and placed on the stoolin the manner illustrated in Figure 3 with the top end of the side pieceoverlapping the top member (11) of the ndow casing. The marker then isagain placed over the side piece with its front edge (3) in line withthe lower edge (13) of the member (11) and with the front edges (7) ofthe flanges (6) bearing on said lower edge. A pencil mark drawn alongthe line 3 will then be in exact alinemen'twith the bottom edge (13) ofthe top member (11) and if the side view (12) is out along this line anexact fit will be obtained irrespective of the angle that may existbetween t(he)side piece (12) and the top member If in marking the sidepiece in the manner described a sharp pencil is used the fit may beslightly longer a pencil with a dull pointmay be used which draws a linea slight distance away from the edge of the marker or a modified form ofmarker such as illustrated in Figure 8 may be used; In the latter casethe front edges (14) of the flanges (16) a form an angle with the upperedges (17) of the flanges slightly under 90 which will cause the frontedge (18) of the marker to slightly project beyond the lower edge of thetop member (13) so that the side piece (12) will be slightly longer itcut along said line and has to be sprung nto its place whereby itsbottom and top edgesare forced into closer contact with the window stooland the top casing member (11). a

In Figure -6 is illustrated the use of my T marker in connection with abase board (19) to be fitted against the side piece (21) of a lowercasing.

The marker shown in Figure 7 is constructed along similar lines butdiffers from son using the same.

Since the plate (2) is rectangular in form it will be readily seen thatthe same may be used as an ordinary square.

1. A marker of the character described comprising a plate havingstraight edges,

oppositely disposed spaced flanges on the plate having portions at oneend projecting an equal distance beyond one edge of the plate and havingtheir opposite end edges terminating flush with the other edge of theplate.

2. A. marker of the character described, comprising a plate having sideflanges thereon presenting parallel front edges extending from the frontedge of the plate and forming an angle of less than 90 degrees with thetop edges of the flanges.
